How about just use train dispatch staff?

How about just use train dispatch staff? Not a bad idea, although dispatch staff are not present on all platforms at all times. |

there is no need to check trains at every platform, if they are reported by dispatch staff as heard then that would be adequate checking.

I'm sure Network Rail have remote wheelset monitoring equipment. In the recent 'Paddington Station 24/7' TV fly on the wall, an HST was taken out of service for wheelset examination with potential flats as it had tripped a detector on its inbound working and if I recall a maximum speed restriction of 50 mph was applied to the set with immediate effect to complete the journey with a prohibition on further use until after examination.

They do, because of the damage flats can do to the track. |

What's the state of play with 72 stock refurbishment/mods? I have not seen the wheelchair bays yet, but I've not been on the line so much this year.

Hmm that video inspires a light bulb moment. As stock on the Bakerloo gets older I guess the risk of wheel flats will rise for any rolling stock which lacks any form of wheel slip detection. That video suggests that you could quickly and easily implement a very cheap wheel flat detection system - assuming there are still signalling staff employed somewhere. Basically as trains shuttle back and forth along the same route it would only take providing the signallers cabin with a simple video camera feed with sound from a nearby platform which all trains are expected to transit. I suspect it would not take very long for the signalling staff to notice any train producing such a loud thump thump sound, and likewise will pretty much ignore the sound of any which don't. Sort of like most car drivers quickly get tuned to what sounds are normal. As and when a train sounds weird, presumably the signallers are ideally placed to identify the affected unit and get the maintenance staff to intervene to swap it out with another train whilst the problem is resolved. For very little investment the Bakerloo could potentially achieve very rapid pay-back through reduced track damage.
Ahem... Wheelchex and Gotcha

Are either of those systems in use on the Bakerloo?

The list at www.railwaycodes.org.uk/misc/habdwild.shtm suggests the only wheel impact load detection system in Greater London is at Queenstown Road Battersea, which is a location not noted for the frequent appearance of Bakerloo line trains. |

Further to carltona 's question, the number of units remaining for structural life extension works at Acton is now into single figures out of the 37 trains in the fleet. |

You may have a gotcha system on the up and down dc electric which the 72 stock travel over.
